wxPython carries on from strength to strength - not only providing bindings for the excellent, multi-platform wx library but also extending beyond the realms of wx with some brilliant enhancements. For anybody considering using wx/wxPython I would also strongly recommend downloading and installing the wxPython Docs & Demos package - the documents are obviously useful but the demos package provides examples of just about every control in wxPython with source code that you can modify and test in place. (See the wxpython dot org site download page for links back to sourceforge for the various doc & demo packages)
